As per the title really. Is there a known term for the trails they leave on surfaces by scraping it with their radula? I thought it might be radulations but the definition of that seems to be ‘manipulate with a radula’ which doesn’t quite fit.
I don’t know of a single word for this. Looking through Google Scholar suggests that scientists use radula tracks, feeding tracks, and/or radular feeding tracks depending on the context.
Also radular [rasping] marks. And if fossil (although not readily attributable to snails), Radulichnus.
Radulinchnus fossils have sent me down a rabbit hole. Some people seem to use the term in a modern context too.
Not shocking in itself, however I can’t fathom the nightmare of maintaining parallel taxonomies on iNat, for organisms and for their tracks&scats If the ‘owner’ of the poop/trace is reasonably known, just use their name.
